DEEP-WELL PUMP. v

SPECIFICATION forming part of Letters Patent No. 515,475, dated February27, 1894.

Application filed March 21, 1392. Seria-l No. 425,811. (No model.)

. ing to be a full, clear, and exact description of the same.

My invention relates to the class of deep well pumps, and it consists inthe novel construction of parts hereinafter fully described andspecifically pointed out in the claim.

The object of my invention is to provide a force pump which isespecially adapted for use in connection with deep wells.

Referring to the accompanying drawings for a more complete explanationof myinventiem-Figure l is a vertical section of my pump. Fig. 2 is across section on line X--X of Fig. l. Fig. 3 is a cross section on lineY-Y of Fig. 1.

.A is a pump pipe extending down into a well, and having within it thevertical reciprocating piston rod B. To the lower end of the pump pipeis secured a pipe C the head c of which is full round either cylindricalor conical, here shown as tapering, and provided with a flange by whichit is bolted to the bottom iiange of the pipe A. The lower portion c ofpipe O is half or part round as shown, with its face c2 concaved ordished. The half round portion c of the pipe O below the concave portionc2 is open to receive the cylinder D as will be presently described. Thebottom of pipe O is closed.

D is the cylinder or working barrel of the y pump. This is secured topipe C and below the concave c2 and fits at its inner side within theopen side of the portion c' as shown clearly in Fig. 3, its upper endbeing open and separated from the bottom of the full round head c ofsaid pipe. The cylinder is formed or provided with external longitudinaliianges D D for securing it to the part c of said pipe O.

Cylinder D is small enough in diameter that lying as it dees in theconcave of the part round portion of pipe C, it does not increase thegeneral diameter of the parts, and will, therefore, tit the well.Moreover it lies in position to receive the piston-rod B which passesthrough the fullround head of pipe C, and through a stuffing-box c3 inthe bottom of said head. It emerges from the head C, extends alongsideof the part round portion c' and enters the open upper end of thecylinder D, in a straight line. Within the cylinder is a piston E ofsuitable character, to which rod B is attached.

The lower end of the cylinder D is provided with a suction pipe F, andwith an upwardly opening suction valve G. An outlet valve H is locatedin the side of the cylinder and controls a communication between saidcylinder and the part round portion of the pipe O.

The operation of the pump is that of a force pump. On the up-stroke, thewater is sucked in through the valve G, and on the down stroke it isforced out through the valve H, and up through the pipes O and A. Beinga force pump, it is best adapted for deep wells in that the work is doneon the down stroke, whereby the weight of the parts is of assistance,while on the up stroke, the windmill or other power does not have tolift the column of water as in lift pumps, but only to raise thepiston-rod. l am enabled to provide a force pump for this purpose byreason of the peculiar construction employed, namely, the pipe O whichis adapted to be connected to the lower end of any pump pipe containingand guiding the piston-rod, and by reason of its shape will receive theworking barrel or cylinder in its side without increasing its owndiameter which perfectly adapts it for use in narrow wells, and locatesthe cylinder in proper position to receive the piston-rod. The upper endof the cylinder being open, prevents any pressure of water above thepiston.

Havngthus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The herein described pump comprising the half round pipe C, formed witha round head c having a packing gland in its lower side, a half roundportion c therebelow and having a closed bottom, the upper portion ofsaid part c being closed on its inner side as at c2 and the lowerportion of said inner side being open, the separate and independent pumpcylinder tting at its inner side into'the open side of the part c withits longitudinal center in vertical alignment with the said gland,l

an opening in the side of the cylinder oommunieating with the interiorof the half round part c through the open side thereof, an ont- Wardlyopening valve on the cylinder for said opening, the inlet valve in thelower end of the cylinder, and the external longitudinal anges on saidcylinder for securing it to said part o', the piston in the cylinder andthe rod Gmcending therefrom alongside .the closed portion c2 up throughsaid gland, substantially as herein described.

h In witness whereof I have hereunto set my and.
